The gen2 intake manifold and TVIS were designed to provide good low end torque and high top end flow using a dual runner per port setup with a set of butterfly valves kept closed at low RPMs to increase air velocity into the port and open at higher RPMs to increase flow capacity. The proper TVIS opening point lowers as VE improves (better exhaust, turbo, valves or cams). The stock ECU keeps a fixed opening point around 4200RPMs which is too high for modified gen2 setups. Consequently, there will be a torque dip from around 3800 RPMs to 4200 RPMs. Many recommend removing or disabling the TVIS to eliminate this bump and improve top end


This Is to stop a restriction on 300+bhp as it isnt needed.. I was going to run the stock manifold but due to power levels i want the manifold itself would restricted me..
